Abstract
An operator interface assembly for a machine is disclosed. The operator interface assembly comprises a base, an operator input device operable to move in a first direction in relation to the base to a second position and a third position, a first biasing member including a first spring end, and operatively associated with the base and wherein the first spring end is operable to contact the operator input device at a first position and resist movement of the operator input device in the first direction, a second biasing member including a second spring end, and operatively associated with the base and wherein the second spring end is operable to contact the operator input device at the second position, the second position different than the first position, and resist movement of the operator input device in the first direction, and a position sensor.
